In response to geohot’s purplera1n, the dev-team has released an update of UltraSn0w for unlocking iPhone which pretty much caters to most of the problems of the previous release. This is what they claim:

 

  • Works on both 3G and 3GS
  • Works on hacktivated devices
  • Works regardless of how you jailbroke your device
  • Doesn’t patch any mach-o binary whatsoever.  (Doesn’t require a separate patch as each new firmware comes out).
  • Doesn’t install any additional daemon
  • Has no race conditions, no popups about “Missing SIM”, no network issues
  • Is almost 7000 times smaller than its nearest competition 🙂
  • Is available now via Cydia.  Source repo is https://repo666.ultrasn0w.com (that last “0” in ultrasn0w is a zero!)
